The tyre places I visit have F20 specifications. My only issue was that the technician I went to said the M135i was the same as all the other F20 M-sport suspended cars and used these settings. He also said the alignment was essentially correct so made no real changes.

A member on Baby BMW has M135i specific settings which he kindly forwarded to me.

If the caster angle is correct, it explains why the steering feel is rather vague on these cars. Maybe electric steering support has nothing to do with it. More caster angle increases the steering centering torque, making it easier to feel how much grip you have left.

The relative lack of caster and camber is how it feels. I had a 3 litre Legacy with similar stock settings - managing to increase castor and get -1.75 deg front camber made a huge difference to the sense that the front end was biting on turn-in, not to mention tyre wear.

I'd eventually like to find out how to do something similar to my 1er.
